Abstract: The display device includes a connection pattern and a dummy pattern spaced apart from each other on a substrate; a via layer on the substrate; a pixel electrode on the via layer and electrically connected to the connection pattern; a light emitting layer on the pixel electrode; a control layer on the light emitting layer; and a common electrode on the control layer. The dummy pattern may include a first dummy pattern and a second dummy pattern disposed on the first dummy pattern. The first dummy pattern may include a first layer, a second layer, and a third layer each of which is made of a conductive material and is sequentially stacked. The second dummy pattern may include an organic pattern including a first portion and a second portion having different areas in a plan view.

Abstract: A method for manufacturing a deposition mask includes depositing a seed metal layer on a front surface of a silicon substrate, forming a first photoresist pattern defining first openings on the seed metal layer, growing a plating layer in the first openings of the first photoresist pattern, forming a mask membrane by removing the first photoresist pattern and leaving the plating layer, depositing a protection layer to cover a front surface of the mask membrane, forming a second photoresist pattern defining cell opening corresponding to unit masks, respectively, on a back surface of the silicon substrate, exposing the seed metal layer by etching the back surface of the silicon substrate using the second photoresist pattern as a mask, exposing a back surface of the mask membrane by etching the seed metal layer using the second photoresist pattern as a mask, and removing the protection layer.

Abstract: A display device may include a first electrode, a second electrode, an emission layer, an intervening layer, and a first encapsulation layer. The second electrode may overlap the first electrode. The emission layer may be disposed between the first electrode and the second electrode, may overlap the first electrode, and may include a light emitting material. The intervening layer may directly contact the second electrode, may be spaced from each of the first electrode and the emission layer, and may include a fluorine compound. A first section of the first encapsulation layer may overlap the emission layer. The intervening layer may be positioned between the second electrode and a second section of the first encapsulation layer.
